SCORING-MACHINE.

Original application filed July 19, 1906, Serial No. 326,839.

30, 1910, Serial No. 584,635.

To all whom "it may concern:

Be it known that I, JOHN G. Jones, citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Scoring- Machines, of which the following is a specification.

In paper-board scoring machines the scoring cutters are removably and adjustably mounted on a so-called cutter-bar which is rotatively mounted in the frame of the machine whereby it may be turned to a position to permit of the ready and convenient adjustment of the cutters thereon, and thereafter be moved to a position to locate the adjusted cutters in operative relation to an op posing power-driven bed-roll over which the sheets of paper-board are fed to be acted on by said cutters. In some instances the cutter-bars of these scoring machines are provided with two sets of cutters arranged at opposite sides thereof, either of which sets may be brought to operative position relatively to the bed roll by a turning of the bar, which is usually done by hand. To provide for the free and easy turning by hand of said cutter-bar for any of the purposes stated or otherwise, its journals preferably have a slight play or looseness in their bearings, and this play, if not wholly taken up before the scoring operation is commenced, prevents the cutters maintaining with accuracy their adjusted cutting position relatively to the opposing bed-roll during working operation. Because of such fact, it has been the main object of my present invention to provide a simple and readily adjusted means for locking or securing the cutter-bar against undue movement in its bearings upon its adjustment to bring the cutters to operative position. The means for accomplishing such object may be of varied construction, one simple and desirable means being that shown and described in my pending application, Serial No. 326,839, filed July 19, 1906, (of which application this present application is a division), and comprising a compressing means, preferably in the form of a bolt, carrying a plurality of movable sleeves having opposing cam or inclined end faces which cooperate when forced together under the action of the bolt Specification of Letters Patent.

Divided and this application filed September Serial No. 703,560.

to move one of said sleeves late-rally to locklng posit-ion; the locking device as a whole being preferably connected with the frame in which the cutter-bar is journaled, and the said laterally movable sleeve thereof being movable to and from a position of locking engagement with the cutter-bar journal, all as hereinafter described in detail and as illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the upper part of a paper-board scoring machine embodying my invention, with a part of the frame thereof broken out to show the location of a supported locking device relatively to one of the cutter-bar journals. Fig. 2 is an enlarged end viewof the same,also with the frame partly broken out at the locking device, similar to that in Fig. 1. Fig. 3 is an edge view of that part of the machine shown in Fig.2, looking from the right of the latter, showing the adjust-ing end of the locking device. Fig. 4 is a side elevation of the two cooperating sleeves of the locking device shown in Figs. 1 and 2. Fig. 5 is a cross-section of one of said sleeves, taken on the line aa in Fig. 4.

Similar reference characters indicate like parts in the several figures of the drawings.

The numeral 1 indicates a hole bored in the end frame post 2 of the scoring machine in a direction transverse to the axis of the journal shaft 3 of the cutter-bar 4. This bore 1 opens into the frame bore 5 forming the ournal bearing of the shaft 3, as clearly shown in Fig. 2 of the drawing. From the inner end of the main bore 1 extends a smaller central counter-bore 6 which is internally screw-threaded to receive the inner threaded end of a bolt 7 having a thrusthead 8 carrying a wrenclrrebeiving stud 9. Around the bolt 7 there is placed an inner sleeve 10, the axial bore 11 of which has a larger diameter than that of the bolt to allow lateral play of the sleeve on the bolt. This sleeve 10 has an inclined outer end 12, and also preferably has a convexed inner end 13 bearing against a shoulder 14: at the base of the frame bore 1, and a transverse recess 15 at its under side corresponding to the curvature of the cutter-bar shaft 3. On the bolt 7 between its thrust-head 8 and the sleeve 10 is loosely placed another sleeve 16 in which the bolt is free to turn and which i has an inclined end 17 preferably slightly rolilnded or conveXed for engagen'ient with the inclined end 12 of the sleeve 10, with which it coiiperates in a manner to be hereinafter describeifl. Fig. 1 of the drawings shows one of these frictional locking devices located in. each frame post 2, 2, for co operation with the opposite end journals of the cutter-bar.

The cutter-bar 1 as shown in the present case has oppositely located dovetail keys 18, 19, to either one or both of which a set of cutters 21 may be attached in usual manner. As here shown but one set of cutters is attached to the cutter-bar, although it is quite usual to attach two sets thereto; the cutter ar preferably being provided with asuitable hand-grasp 2 1v as a convenient means to permit the operator to turn the unlocked bar by hand in its ournal bearings to bring either of its two sets of cutters into operative relation with the bed-roll 22.

In Fig. 2 of the drawings, the cutter-bar journal. bearings 5 are shown somewhatlarger than in. practice to more clearly illustrate the operation of the invention, which is as follows :After a set of cutters has been brought into operative relation with the bed-roll 22 and before operation of the machine, the bolts 7 in the end frame posts 2, are turned in or tightened by applying a suitable key wrench to the bolt studs 9. This forces the outer sleeve 16 against the endwise stationary inner sleeve 10, the lateral play of which latter on the bolt allows the cooperating inclined or cam faces 17, 12, of the two sleeves to force the gripping face 15 of the sleeve 10 tightly against the shaft 3 of the cutter-bar and clamp the same against movement in its bearings, thereby serving to positively maintain the cutters in adjusted position relatively to the bed-roll and cause them to operate with the desired accuracy in scoring paper-board to the required depth. The inner convexed ends 13 and 17 of the sleeves 10 and 16 respectively, and the enlarged bore 11 of the sleeve 10, permit said sleeve 10 to automatically ad-- just its gripping face 15 to the shaft 3 under pressure of the bolt 7, described.
